SPECIFICATION forming part of Letters Patent No. 680,192, dated August 1, 1899.

Original application filed May 16, 1898, Serial No. 680.834. Divided and this application filed February 1, 1899. Serial No. 704,117. (No mcdeLl f (all whom. it may ('U/Ilffll'll Be' it known that we, An'rnonlnnvon DA,\V son and GEORGE THOMAS BUGKHAM, citizens of England, residing at No. 28 Victoria street, \Vestminster, London, England, have invented certain new and useful improvements in Extracting Mechanism for Breech-Loading Guns, (for which we have applied for patents in Austria,dated September9,1898,No.14,752;

in Denmark, dated September 6, 1898; in France, dated September 6, 1808, No. 268,988; in Germanjgdated September 5, 1898; in Great Britainjdated October 20, 1897, No. 24,204; in Italy, dated September (3, 1898, No. 14,752;

[5 in Norway,dated September 6, 180$,N0. 10,226;

in Spain, dated September-6, 1898, and in Sweden, dated September 6, 1898,) of which the following is a specification, being a division of ourapplication for Letters Patent filed May no 16, 189 Serial No. 080,834.

Our invention relates to improvements in extracting mechanism for breech loading guns, as we shall describe, referring to the accompanying drawings.

Figure 1 is a transverse section of the breech of a go 11 with cartridge-extractor in elevation. Figs. 2 and are plans, partly in section, showing the breech closedand opened,respectively; and Figs. -t and 5 are corresponding views,

0 drawn to an enlarged scale, of part of the extractor and the hammer.

These improvements were originally included in our application filed May 16, 1898, Serial No. 680.834, but. have been made the subject of a newapplication, a division having been required by the examiner.

In a lateral hole in the breech of the gun we fit an extractor-rod e, having its end sloped off, so as to engage in front of the tla'ngefof 0 the cartridge-case F. The rod 6 is prevented from turning by a projecting stud e, engaged in a lateral groove, and the outer end of the rod is made with aslot e on its rear side and a projection e on its under side. On the boss of the breech-plug carrier 0 are fixed a ham merarm h and two projecting partsh and 72- 71/2 being in the plane of the slot 2 and h in the plane of e". When the cartridge F is in place and the breech is closed, the rod 6 is in the position shown in Figs. 1, 2, and 4. On throw 5e ing back the carrier 0, as shown in 3, the hammer-arm It strikes the head of the rod 6,

pushing it inward,so that its sloping part,

acting on the flange f, starts the extracting movement of the cartridge-case. On again closing the breech the projection 71., acting on the projection 6 causes the rode to move back to the position shown in Figs. 1, 2, and 4.

The projecting part 71*, engaging the groove 6 prevents the rod from being moved acci- 6o dentally out of position when the breech'is closed.

Having thus described the nature of this invention and the best means we know of carrying the saineinto practical effective claim-- In a breech-loading gun, the combination of the breech-plug carrier having a hammer-arm h and two projections h and 77. and a sliding rod 6 having at its'outer end a slot and projection engaged by the projections on said carrier and having its inner end sloped to engage in front of a cartridge-flange, substantially as described.

In testimony whereof we have hereunto set our hands in presenceof two subscribing witnesses.
